Abstract

In the present manuscript, we report for the first time Cu ₂ZnSnS₄ (CZTS)-based heterojunction (p-CZTS/n-ZnO) used for room temperature liquefied petroleum gas (LPG) sensing. Specifically, the nanostructured ZnO has been grown chemically onto the sputtered CZTS thin films. The formations of phase pure CZTS and ZnO are confirmed by X-ray diffraction studies. The high quality heterojunction between compact CZTS and nanosized ZnO is obtained. At room temperature, the CZTS-based heterojunction exhibited gas response of 19.3% upon exposure to 1200 ppm of LPG with faster response and recovery time of 70 and 40 s.
